The average Joe cannot restore this AC. First, you need all certified parts, that means manuals. Then you're gonna need the worlds most generous AI to fill out the 337s that you are going to generate... not to mention the self produced items that will need a sign off.
The average Joe does not have the previous experience to work fabric, nor wood repairs. 99% of the A&Ps can't work fabric or wood repairs (see FAR 65.81):
"However, he may not supervise the maintenance, preventive maintenance, or alteration of, or approve and return to service, any aircraft or appliance, or part thereof, for which he is rated unless he has satisfactorily performed the work concerned at an earlier date."
At best the unless the 'average Joe' had a rather large pile of money they want to turn into a significantly SMALLER pile of money this is not a realistic project.
Lastly, the cost of recovering, paint, return to service and annual would be double or more the cost of an already flying project.
